Someone else pointed out that mutex_lock() is a problem here too. They wondered whether spin_lock_irqsave() would work - or whether pstore backends were allowed to sleep - to which I said I hoped they didn't, but wasn't really sure what the future will hold.
So ... ideas (and patches) are most welcome.
